Did some rough number crunching. An overclocked 2600k does 45-50k PPD (correct me if I'm wrong). My Arima AND my 955BE combined do about that. OK, well, the 2600k is a few years newer after all. But then, the power consumption numbers... ouch. Between the two rigs I'm using at least 750 watts from the wall. A 2600k box uses what, 300 watts?
Now I'm thinking I should have jumped on that sick Microcenter board + CPU deal they had going on - the one that was stackable with the extra $50 off facebook coupon - and then sold my Arima and my 955BE setup. I could have at least broken even on that I would think! Assuming I could find a buyer for my Arima, it is a rather specialized rig really.
I guess I wasn't too smart.
Oh, and as a side note, while my i7 does pretty good at crunching (even at stock speeds, I can't overclock it unless I lap the thing, concave IHS), I really don't like it for day to day usage. Maybe it is because it is crunching, I don't know, but it is not a very refined system. The numbers don't lie, it performs very well, but the experience with it is, well, very stuttery and jarring. My 955 while slower is, ah, "smoother" by far (don't smack me! ).
Maybe I should look at selling some stuff here soon and keeping my eyes open for another microcenter combo deal...
